FURNACE.

Application filed February 25, 1927. Serial No. 170,807.

This invention pertains to improvements in furnaces. More particularly the invention pertains to means for mounting certain parts of a hot air furnace with respect to one another.

An object of the invention is to so attach a bracket to the main heating drum of a furnace that leakage of gases from said drum cannot occur, said bracket being employed for connection therewith of a sup porting part for an auxiliary heating drum connected with said main drum.

Another object is that of providing such a form of means for attachment of said bracket to the main drum that a considerable amount of time and labor is saved due to the ability to readily and quickly set up or disassemble the parts.

As an aid to the understanding of my invention the accompanying drawings are provided wherein,

Figure l is a plan of a furnace, showing parts in section, wherein my invention is used.

Figure 2 is an elevation of the furnace showing a side elevation of parts entering into the invention.

Figures 3 and 4: are respectively a front elevation, and a plan of a notched bracket, 30 and Figure 5 is an enlarged elevation of parts shown in Figure 2.

The type of furnace described herein is one in extensive use by reason of its thor-- oughly gas-tight construction, the invention herein in connection with such furnace being based upon the idea of maintaining this gas-tight form while providing for rigidly connecting certain parts to a main heating drum.

In said drawings the numeral 1 designates the body of the furnace which takes the form of a closed welded and riveted drum surmounted by a domed portion 2 also welded and riveted thereto, 3 denoting a front portion welded and riveted to the body and provided with the usual coal-door throat portion 4 and ash door extension 5.

Likewise welded and riveted to the rear of the body 1 near its top is the flange 6 of a smoke outlet stub 7 A11 auxiliaryradiator or heat drum is shown at 8 which takes the form of acrescent as viewed in plan, Figure 1, and includes flanged heads 9, but one of which is shown, which are welded and riveted to the main body. EX- tending from the co'hcave side of the radiator or drum 8 near its top is a pipe stub 10 welded and riveted to 11 of said stub, a second flange 12 of the the same at the flange latter being bolted to the flange 7 of the stub 7, the joint between the two being made gas tight by means of a gasket, not shown. At the convex side of its bottom is welded and riveted a pipe stub 13 extending through and outside the furnace casing 1 1 and receiving the smoke plpe 15.

The above structure has been described thus fully in order to show the tight and leak proof form of the furnace which idea is to he maintained in adding structures to be touched upon herein.

The said radiator or auxiliary drum 8 is, of course, of some considerable weight and must be supported by means in addition to the pipe stubs 7 and 10 described. And preferably the supporting means is attached to the body 1 in order to create a unit throughout and to better preserve the equilibrium of the entire structure.

the radiator 8 near 7 The supporting means is preferably made its lower end upon the step 16 and may be f secured to said step in any suitable manner if desired, said brace being spaced from the body 1 so as to lie beneath the radiator at the most advantageous supporting position of that member. The: upper portion of the brace extends toward the body 1 and is supported thereby, as will appear presently, and attached to an upright leg of the brace is a member 18 which receives the weight of the radiator upon it, said member being adjustable for height upon said brace through the use of bolts 19, there being a slot 20 in the member to permit such adjustment.

Figures 3 and 4 show a bracket 21 adapted for attachment to the body 1. It includes an extended middle portion 22 lying outside the plane of the end portions of said bracket, the same being provided with a notch 23 and may include a bottom extension 2 1 to lie below the recess created by extending said middle portion as described. The extremities of the bracket are perforated so that each may receive a rivet 25 by means of WlllOl'l said bracket may be secured to the body 1. The recess in said bracket receives the head of a bolt 27 carried by the brace 17, the shank of said bolt entering the/said notch 23. The step 16 is supported on the body 1 through the use of a similar bracket identitied in Figures 2 and 5 by the same reference characters, a bolt 28 serving to connect the said bracket'and foot as in the first instance.

By tightening the bolts 27 and 28 the Whole radiator supporting structure is held to the body l'in a firm and thoroughly stable manner.

Due to the fact that the body 1 mustbe maintained thoroughly gas-tight the brackets 21 are riveted in place, and they may be welded in addition, so that leakage of gases is entirely prevented which would not be the case if the bolting method were employed. This is doubly important when fuel oil is used as the heating agent. That is to say, because of the fact that theradiator hangs far outside the'center of gravity of the body 1 it must, of course, be properly supported,

and in order to provide for the greatest stability and rigidity of the whole the supporting structure is attached to the said body 1. Since this is desirable the bracket 21 must be attached to said body in such manner as to preserve thelatter gas tight as arequirement.

My'deviceis simple in construction and has the advantage that it may be quickly set up, and that it is positive in results. The step 16 due to being attached at one end to the drum 1, and having a single foot portion surface.

at one end to rest upon the floor does not require a level surface on which to rest, the single leg insuring a firm support on any The notched brackets 21 provide for quickly setting up the aflair or for disassembling it. V

I claim:

1. The combination with a main heating drum or body of a furnace, and an auxiliary drum, of a supporting means for the latter placed beneath the same including a step, a brace mounted on the step, a member adjustable vertically upon the brace, and means to secure the member and brace in rigid relation, and a pair of brackets secured permanently to the main drum at difierent levels, each including an open notch, a part on the brace and a part on the step for en gaging in the notches of said brackets.

2. The combination with a heating drum or body of a furnace and an auxiliary drum attached thereto and extending laterally therefrom, of a bracket attached permanent- .ly to the first named drum below the level of said auxiliary drum and extending outward and having a notch therein a step portion, a part at one endthereof to engage in said notch, said step portion terminating at its other end in a depending foot portion, a brace mounted on the step beneath the auxiliarydrum, a second bracket permanently attached to the said first drum above the first named bracket and also having a notch therein, a part on the brace to engage in the notch, and a member attached adjustably to the brace adapted to engage the bottom of the auxiliary drum supporting the same, the said brace and said step being separately removable from the brackets.

In testimony whereof I affix my signature.
